1. Adjacency matrix view of the 24 subjects

One random subject:

The adjacency matrix of the whole brain.

Segments: Bottom left: Left Hemisphere Upper right: Right Hemisphere

On average:

Segments: Bottom left: Left Hemisphere Upper right: Right Hemisphere

Compare left and right hemisphere in average

Degree plot by ROI index

Degree distribution

Use of dimension reduction:

We applied joint embedding on the 24 subjects and extract the diagonal distinct vectors

Pairs plot of the first 5 dimensions:

## `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
## `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
## `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
## `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
## `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.

Average scree plots of the 3 groups:

From the low dimension representation, old group looks distinct from the middle and young groups. This is consistent with the finding in the adjacency plots.
